MACHINE FOR AUTOMATICALIY MAKING- SOLDEBED. CABLE AND SHAPED CHAIN S.

To all whom it may concern:

Be itknown that I, LUDWIG BRUeKMAniI, acitizen ol the.German Empire,residing at Pforzheim, the .Grand Duchy of Baden, Empire of Germany,have invented certain new and useful Improvements inMachinesforAutomatically Making'Soldered Cable and Globular or PeaShaped Chains, ofwhich. the following is a description, reference being had to theaccompanying drawing and to the letters and figures oi reier- 'encemarked'thereon This invention relates to an improvement in the machinesfor automatically making soldered cable and globularor peashaped chains,and this improvement relates more particularly toanautomatic arrangementfor soldering such chains. By the present invention these operations,that is to say, the application of the soldering fluid or flux, thetouching with solder and the heating oi the chain, and more particularlyits conveyance, are performed automatically. The links of the chain mustbe suspended connected, that is to say, the joints of each two linksmust be constantly in contact.

By the present invention the forward movement of the chaintakes place bymeans of a spur or pin which for this object engages in the aperture ofalink and.

7 driving gear common to all. The cut off piece of solder passes into-achannel from which it is ejected by an ejector and comes direct to theplace in the chain links which is to be soldered. In consequence of theapplication of the soldering flux, the solder remains adherent on thechain and-passes with it to the soldering flame which serves to fuse thesolder, whereby the links are automatically closed.

The. invention .is shown in the -accom'paying drawings', in which,

Figure 1 is a front View; and Fig. 2, a plan View .of the machine as awhole; Fig.3, a side view on an enlarged scale and partial sectionshowing the .projecti'on of the solder; Figs. 4 and 5 are rear and sideviews respectively of the devices for moving thechain and applying thesoldering flux; Fig. 5 is a dc tail iew illustrating the progressivemovement of the chain; .FigQG, a plan view of Fig.- 4; Figs. 7 and 8,front t and side views respectively and a plan view of the cut- .ofii-of.the solder.- Fig. 9 is a plan view oi-the Specification of LettersPatent;

Fig. 13 is a detail sectional view of the guiding mem- .This runs fromhere over aguide roller 5 to the chain It thus executes a doublemovement, namely, an upenters the aper- Ward movement for engaging therespective link of'the chain, and thena lateral movement. For thepurpose of the upward movement the spur 10 is mounted ona lever 11standing under the action of a spring 25 and pivotally mounted on a pin12 of an arm 13. ,The arm 13 is carried by acarri age 14 which travelsin guides 15 on standards 9. The carriage '14 is under the action of aspring 16 and is moved by an eccentric a which is mounted on a. spindle18 which is revoluble in bearings 19. This eccentric'is driven from adriving pulley 23 which is mounted on a spindle 21 revoluble in bearings22, the transmission of the rotary motion taking place by means of gearwheels 20. A roller 17 is revolubly mounted on the carriage 14 for thepurpose of diminishing friction, which roller travels on the eccentrica.

Thelateral movement is; imparted to the arm 10 by meansvoi a cam disk balso mounted on the shaft 18, which cam disk moves the end of thetwo-armed lever 11, which end is provided with a roller 24, and. mayberegulated by means of 'an adjustable catch 75. Hereby the chain Zisied, traveling in guides. These guides consist of a ie of fixed checkplates 6 and a hinged plate 7. The several plates are grooved. to formV-shaped guiding channels "for ,one series of chain links, while theother series is guided betweenthe plates 6 on one side and the plate 7on the other. The movable jaw 'Z is held down-in closed, position by aspring 8.

By the sinking of the carriage 14, when accordingly the spur 10 doesnotengage in a chain link and thus the chain 2 is stationary, thesoldering flux is applied. For this object the carriage'la, carries asoldering flux container 26 which is arranged on a support 30 andprovided with a small pipe 27 in the aperture of which E a sponge 28 orthe like is inserted. with which the 1 soldering flux is supplied. Nowwhen the carriage 14 sinks. the sponge 28 which is always saturated withthe soldering flux encounters the joint of two chain 3 46 of leather orthe like which is arranged on the fixed -by a spring 65.

arm 49 and prevents any slipping back of the wire 42 (Fig. 3). From thebrake 46 the wire 42 reaches the conveying apparatus. This consists ofa'pl-essure bolt standingunder the action of a spring 51, which bolt ismounted in a projection or shoulder of the carriage -l7 sliding in'theguides 49 on a block 48, which carriage is moved by a cam disk a mountedon the shaft 39. In the forward movement of the carriage 47 thesoldering wire is clamped by means of the pressure bolt 50 by aneccentric d mounted on the shaft 36, which moves I a lever 53 standingunder the action of a spring 61 and pivotally mounted on a pin 54, whichlever in turn by means of its pressure roller 52 depresses the bolt 50.The shaft 39 mounted in the bearings 40 is'operated from the shaft 18 bymeans of gear wheels 41, the rotary motion being transmitted to theshaft '36 which is revoluble in bearings 37, by means of bevel wheels38. The soldering wire 42 now passes from the conveying apparatusthrough an aperture-55 of a plate 56 forming the fixed jaw of thecutting appliance, and

is projected each time so far as is necessary to supply -a piece ofsolder of suflicient size for soldering the chain.

The projecting piece is now out oft by a knife 32 formed as alever, which knife is mounted on a pin 33 pivotal on the fixed jaw 56and which its-operated The movement of the knife 82 is produced by a cam.disk 0 mounted on the shaft 36, on which cam dish an adjustable roller35 travels. The cut off piece of soldering wire passes into a channelwhich is provided in a suitably recessed plate 57 arranged under theknife 32 and which prevents the cut ofipiece of solder from springingout. A movable dog 58 extending up to the kniie 32 is also provided,

which dog is pivoted on the pin 59 and is under the action of a spring60, by which arrangement the cut ofi particle of solder comes withcertainty into the channelwhereuponit is expelled from the channel bythe'ejector .62 and laid on the soldering place. It

After the chain '2 is provided withsolder it passes; traveling over a roller 71, to the soldering flamewithin a protective casing 72. The flame is fed in the i ordinary ,wayfor obtaining a great heat by "a mixture of gas and which is com eyed toit' through pipes 73 and 74.

The method of working of the machine is as follows:l.he spur firstenters a chain link and pushes a fresh soldering place under the solderejector. On

the return of the spur 10,the next soldering place is also moistenedwithsolderin'g flux by the sponge 28. In the meantime a piece of solderis out off by the knife 32 and thrown by the ejector 62 on thesolderingplace I where it adheres in consequence of the application of thesoldering flux, after which the chain, which has reached the solderingflame, is there automatically soldered, the piece of solder being heldin place by ad-. hesion of the flux and being fused when subjected tothe heat of the flame.
